[Piglit] [v6 06/12] tests: spec: EXT_image_dma_buf_import missing attributes

[Topi Pohjolainen]

v2:
   - compile only on platforms that have drm (Eric)
   - use standard drm definitions for fourcc instead of duplicated
     local (Daniel, Eric)
   - removed irrelevant quotes of the spec (Eric)
   - rewritten attribute test vector using a full set which is then
     trimmed down in individual tests (Eric)
   - check that EGL did not take the ownership and revise the
     explanation for it (Eric)
   - use helper variables for width, height and cpp instead
     of repeating the magic numbers over and over again (Eric)
   - use the stride and offset provided by the framework instead of
     hardcoded assumed values (Eric)
